Each metal has a different emmission spectrum because each metal has a different configuration of electrons. Since electrons can only emit specific amounts of energy and E=hv, where E=energy h=Planck's constant and v=vibrations per second, and E stays the same and h stays the same, the vibrations differ. Different vibrations mean different spots on the electromagnetic spectrum, and so there are different colors.

Are transition metals highly coloured?
The transition metals themselves are not particularly highly coloured. Gold is golden, copper is copper but the majority are grey or silver with a greater or lesser degree of shine.The compounds formed by transition metals (as opposed to those of group one and two metals) are highly coloured and as with all metals they all burn with distinctive flame colours.
Why do yule logs burn red and green?
Some Yule logs that are available commercially have green and red flames when they burn. The chemicals that cause the colored flames are barium and strontium.
Do lighter colored candles have more wax then darker colored one?
light coloured candles do burn faster than darker coloured candles for one main reason. The darker the candle, the more dye molecules are involved in the candle which are non-flammable. Therefore, the lighter the candle, the less dye molecules are involved minimising the risk of the dye molecules interfering with the combustion process.
Does fire feed on oxygen?
Definitely yes.... Fire needs oxygen to burn... If that specific place in which fire is burning, runs out of oxygen, the flames will get extinguished. You can try this by covering a burning candle with an airtight box...
Why are luminous flames preferred?
The temperature is higher and the soot is minimal.
Why does the hydrogen produced in the reaction between dirfferent alkali metals and water burn with different colour flames?
the "metals - not hydrogen" burn with different coloured flames.... 1) metals possess delocalized electrons. 2)when heat is added, the electrons are "excited" and therefore jump from their stable ground state to a highher energy level. 3)as this higher energy level is more unstable, the electron has a tendency to "deexcite" and return to it's ground state. 4) this produces diff frequencies which happen to fall within the visible light of the spectrum.

What colour of flame does potassium burn with?
Potassium has a 'LILAC' ( pale purple) flame. Group (I) metals Lithium = Red Sodium - Yellow Potassium = Lilac. NB Other metals have coloured flames. Copper being the most well known , with a blue/green flame.
What are the properties of the alkaline earth metals?
They are shiny, silver, less malleable than alkali metals and they burn with bright flames. They also make strong bases (Opposite of acid).
Can graphite burn and produce flames?
Yes, graphite can burn and produce flames when exposed to a high enough temperature.
Why do flames have red orange and yellow?
the flames can be different colors. it just depends on what you burn. fireworks for instance if it is red copper is what burning. If you burn colored news paper it turns green.The hottest fire is white fire.
